- the shaft with the stirring device can also be attached to the outside of the fermenter.
- the stirrer comprises at least one drive and a wall-mounted stirrer shaft bearing fastened to the wall of the fermentation container, a further fermenter-side stirring shaft bearing resting on the ground and at least one stirring shaft with stirring blades.
- the stirring shaft extends parallel to the bottom of the fermentation tank in the direction of the main axis of the fermentation tank.
- the present invention is based on the object to provide a device for mixing the contents of substrate containers, especially in biogas plants, which has a high performance, is very well adapted to the changing conditions during operation of the biogas plant and in maintenance low disturbances of Operation caused. Not only a local turbulence of the content should be done, but the entire contents of the substrate container to be set in motion.
- the advantages of the device according to the invention for biogas plants lie in their high performance, their stability, their ease of maintenance and their ability to move the entire contents of the substrate container in motion.
- An apparatus for mixing the contents of substrate containers by means of an agitator is advantageous, in particular, if the substrate container comprises at least one circumferential wall and a bottom, and if the peripheral wall is oriented on a vertical main axis, the agitator comprises a shaft which under a Incidentally extending from the vertical and horizontal mounting angle ( ⁇ ) protrudes into the substrate container, if further the agitator is connected to a buoyant body and depending on the liquid level in the substrate container in the longitudinal extent of the shaft on this slidably, but rotationally disposed, and if the agitator at least two stirring blades includes diametrically extending on both sides of the rotatable shaft and are alternately in the content of the substrate container during rotation or protrude from it.
- ⁇ vertical and horizontal mounting angle
- stirring blades are arranged above the buoyant body.
- the shaft is designed in several parts and has a prismatic outer shell, and if the buoyancy body has a guide which receives the prismatic outer shell of the shaft.
- a device is designed when the shaft of the agitator is supported on the bottom of the substrate container.
- a device is advantageously constructed when the support of the shaft at the bottom of the substrate container by means of a bearing block takes place.
- a device may also be advantageous if the shaft of the agitator penetrates the cover of the substrate container
- a device is especially favorable designed when the substrate container is designed as a fermentation tank, Nachgär hereer, repository or the like.
- peripheral wall of the substrate container in the plan view is circular ring-shaped.
- a device is advantageous if the stirring blades extend into their end regions radially to the shaft have extending rectangular profile, the end portions opposite the extension direction of the rectangular profile, however, have angled portions.
- FIG. 1 an open substrate container is shown, which is referred to in the following description as a fermentation tank 1 a biogas plant 2.
- the content is to be mixed by a stirrer 3, which are arranged in this embodiment in a cylindrical fermentation tank 1.
- a wall 4 of the fermentation container 1 is preferably thermally insulated and preferably made of concrete.
- the upper boundary edge 5 of the fermentation container 1 has a reinforcing plate 6, by means of which a drive motor 7 for a stirring shaft 8 - shielded in a gastight manner - is mounted on the fermentation container 1.
- the agitator shaft 8 projects into the fermentation vessel 1 at an installation angle ⁇ deviating from the vertical and horizontal, and carries two agitating blades 9 and 10, which are mounted diametrically on the agitator shaft 8. At its end facing away from the drive motor 7, the agitator shaft 8 is supported in a bearing block 11, which is located at the bottom 12 of the fermentation tank 1.
- the agitator shaft 8 is designed in several parts and consists of a driven by the drive motor 7 shaft 13 and a prismatic outer shell 14, which surrounds the shaft 13.
- a buoyancy body 15 is mounted longitudinally displaceable.
- the buoyant body 15 consists of a hollow cylindrical floating body 16 whose central longitudinal axis is realized by a guide 17 for the prismatic outer shell 14 of the agitator shaft 8.
- the buoyancy of the float 16 is dimensioned to correspond to the liquid level 18 of the substrate 19 (see FIG. FIG. 2 ) follows. Since the stirring blades 9 and 10 are arranged above the floating body 16, it follows from this design that there is always one stirring blade 9 or 10 inside and the other outside the substrate 19. The consequence of this situation is a rhythmic immersion of the stirring blades 9 and 10 in the substrate 19, which leads to a formation of the substrate 19 in the fermentation container 1. This wave ultimately rotates within the fermentation tank 1 and thus the entire substrate 19 moves in the form of a wave through the fermentation tank 1.
- FIG. 2 the agitator 3 is shown in side view.
- identical or identically acting components are provided with the same reference numerals as in FIG. 1, to which reference is expressly made.
- the stirring shaft 8 With the aid of the drive motor 7, the stirring shaft 8 is set in rotation and the stirring blades 9 and 10 move the substrate 19 (whose fluid level is shown here as line 18) in the fermentation tank 1 in motion.
- the stirring blades 9 and 10 - as described above - dive more or less into the substrate 19.
- the substrate 19 is not only fluidized locally on the propeller, but the entirety of the substrate 19 is rotated by the stirring blades 9 and 10 within the fermentation vessel 1 in rotation.
- the stirring blades 9 and 10 have at their end portions 20, 21, 22 and 23 bends 24, 25, 26 and 27.
- the stirring blades 9 and 10 are preferably made of sheet steel and bent prismatic, so that in the stirring direction - which corresponds to the direction of rotation of the stirring shaft 8 - each gives a prismatic profile 28 with the cross section of a ship's bow 29, whereby the forces are kept low during stirring in the substrate 19.
- the angled portions 24, 25, 26 and 27 optimize the shape of the stirring blades 9 and 10 so that the effective areas of the stirring blades 9 and 10 are as close as possible to the edge portions of the fermentation tank 1, maintaining their stirring action in these areas because of the blade effect is stronger than in a propeller-like round-ended end of the stirring blades according to the prior art +. This applies both to the areas of the wall 4 and to the bottom 12 of the fermentation container 1.
- FIG. 3 3 shows an agitator 3 in a variant in which the stirring blades 30 and 31 have the cross-section of a narrow blade 32.
- the positioning above the float 16 and the orientation of the blades 32 to the longitudinal axis thereof is chosen so that the lowest possible immersion in the substrate 19 results.
- the stirring blades 30 and 31 are designed differently, although the same movement of the waves of the substrate 19 as in the apparatus according to the FIG. 1 as well as the FIG. 2 is achieved.
- FIG. 4 schematically the buoyancy body 15 is shown, which forms the float 16 as a cylindrical hollow body.
- a guide 17 in which the prismatic - square here - outer shell 14 of the stirring shaft 8 is mounted longitudinally displaceable.
- the longitudinal displacement allows the float 16 with his agitator 3 to follow the liquid level 18 of the substrate 19.
- the prismatic design of the outer shell 14 and its torsional strength in the guide 17 causes the rotationally rigid entrainment of the agitator 3 on the agitator shaft 8. It is understood that the float can also be implemented as differently designed buoyancy body.
- the agitator shaft 8 is shown with its essential details.
- a core there is a shaft 13 on which a prismatic - here square - outer shell 14 is arranged.
- On the outer shell there is at least one stop 33 which limits the float 16 in its axial movement.
- Flanges 34 and 35 serve to attach the agitator shaft 8 on the drive motor 7 and the bearing block 11th

Abstract
Die Erfindung betrifft eine Vorrichtung zum Durchmischen des Inhalts von Substratbehältern (1). In dem Substratbehälter (1) ist ein Rührwerk (3) installiert, dessen Rührschaufeln (9, 10) oberhalb eines Auftriebskörpers (15) angeordnet sind, wobei der Auftriebskörper (15) dem Flüssigkeitsniveau (18) des Substrats (19) im Substratbehälter (1) folgt. Die axiale Position des Rührwerks (3) auf der Rührwelle (8) ist somit abhängig von der Höhe des Flüssigkeitsniveaus (18) im Substratsbehälter (1). Bei Rotation des Rührwerks (3) wird durch das rhythmische wechselweise Ein- und Austauchen jeweils einer Rührschaufel (9, 10) eine rotierende Woge des Substrats (19) im Substratbehälter (1) erzeugen.The invention relates to a device for mixing the contents of substrate containers (1). In the substrate container (1), an agitator (3) is installed, the stirring blades (9, 10) are arranged above a buoyant body (15), wherein the buoyant body (15) the liquid level (18) of the substrate (19) in the substrate container (1 ) follows. The axial position of the agitator (3) on the agitator shaft (8) is thus dependent on the height of the liquid level (18) in the substrate container (1). Upon rotation of the agitator (3), a rotating wave of the substrate (19) in the substrate container (1) will be generated by the rhythmic alternately immersion and withdrawal of a respective stirring blade (9, 10).
